CONSTRUCTION OF CHURNS.

Specification of Letters Patent No. 2,758, dated August 25, 1842.

To all whom, 'it may concern Be it known that I, NOAH H. LINDLEY, ofRedding, in the county of Fairfield and State of Connecticut, haveinvented a new and useful Apparatus for Churning Butter and for Freeingthe Same of Buttermilk, which may also be used to facilitate many otheroperations to which it may be successfully applicable in the arts.

The following description taken in connection with the accompanyingdrawings forms a full and exact specification of my invention, wherein Ihave set forth the nature and principles of it, by which it may bedistinguished from others of like character together with such parts orcombinations of the same as I claim and for which I solicit LettersPatent.

Figure 1, of thedrawings above mentioned, represents an end elevation ofmy machine. Fig. 2, is a top view of it. Fig. 8, is a central andvertical section, while Fig. 4, is a side elevation of the vibratingdasher as removed from the reservoir or tub.

The peculiar object of my improvement is to discharge or work thebuttermilk from the butter, after the formation of the latter, and by avery simple arrangement and operation, as will be hereinafter moreparticu-V larly explained.

The mechanism of my improvements consist in a reservoir or tub A, Figs.1,2, 3 (whose bottom and sides are curved as seen at a, b, c, in Fig. 3,and whose ends are vertical, the curve of the sides of the reservoir Abeing a portion of a circle, somewhat greater than a semicircumferenceas denoted .by the drawings), and a vibrating `dasher' B.

The dasheris composed of two vertical pieces d, CZ, Figs. l, 8, t,united near .their middle parts by a transverse bar 0 F ig. el,

`and at their tops by another bar d, (and which is also the handle bywhich a person may operate the machine), andeach having a bar or pieceof wood e, suitably applied at right angles `to it as seen in thedrawings the said cross bars e, e, having two Scrapers or float-boardsj,V f, extending from one to the other of them, and so arranged that theedges of the Scrapers or floats may be in contact or nearly so with theinterior of the other suitable roller g is also applied to and revolvesin the lower ends of the side pieces (Z, CZ, the circumference of saidrollers, being in contact o-r nearly so with the curved bottom a b c ofthe reservoir. The journals of said iluted roller revolve in suitablebearings formed in the side pieces CZ, CZ, which latter are furtherconnected together by a cylin- V drical bar or piece of wood 7L, whoseends extend beyond the side pieces d, d, so as to form journals uponwhich the dasher is suspended or connected to the ends of the box orreservoir, and which play or move in suit able bearings therein formed.Therefore when the dasher is inserted in the reservoir, by applying thehand to the bar cZ",it may be vibrated or moved to and fro therein orinto a position on either side of its center of motion as represented bythe dotted lines in Fig. 3.

The upper or open part of the tub or reservoir may be covered bysuitable inclined lids or boards z', Figs. 2 and 3, which may bereceived or slid into grooves properly formed in the ends of the tub, ormay be otherwise suitably arranged.

The operation of the above machine is as follows. The reservoir beingproperly filled with cream and the dasher moved back and forth', butteris soon produced, the rotary movement o-f the fluted roller g, caused byits resting in contact with the interior of the curved part of thereservoir, together with the action of the floats or Scrapers, creatingsuch an agitation o-f the fluid, as to greatly facilitate the process ofchurning; and when the same is completed, the buttermilk may be drawnfrom thetub A (through a plug `hole 7c, suitably formed through thelower part of one end of the reservoir), the butter remaining therein.`By continuing to vibrate` the dasher the fluted roller spreads or rollsthe butter over the curved bottom of the tub at each vibration thereofthe same being scraped up and raised or turned over by the advancingfloat or scraper f, and so thoroughly is the butter thus operated upon,that the buttermilk is effectually discharged therefrom and flows outthe plug hole 7c.

Having thus described my invention I The combination of the vibratingfloats or Scrapers, fluted roller of the dasher and the provements Ihave hereto set my signature stationary bottom of the reservoir, theWhole this twenty second day of June in the year being constructed `andoperating together eighteen hundred and forty tWo.

substantially in the manner and for'the pur- N. H. LINDLEY. poses asYherein before set forth. Witnesses: y i
